*713,128, filed May'l l, 192 1, or in any other 7 suitable cabinet,

The primary object of our invention is to provide a combination phonograph and radio apparatus in which either the phonographor the radio apparatus may be used, selectively.

Another object is phonograph and radio apparatus in which the amplifying hornnormally used with the phonograph may be used at will as the amplifying horn for the radio apparatus. More specifically, the object of-our invention is to provide a valve operable from the outside of the cabinet to connect the amplifying horn with the tone-arm ofthe phonograph or with the loud speaker of the radio apparatus, at will. Y

' have shown anem'bodiment of our invention,

Fig. 1 is afront elevation of a eabinet embodying our invention. .Fig. 2'is a vertical se tion through Fig. 1.

Fig. 3 is a section on the line 3-3 of. Fig. 2, and

Fig. 4 is a section on the'line 4-4 of Fig.2.

' horn is received in. a block 8,;extending through which. is a passage 9. Connected to the other end of the block 8 is.the neck 10 to connect the block with the tone-arm 6. As is well-known in theart, the sound waves pass through the tone-arm 6, neck 10 and block 8 to the amplifying horn 7. I

We provide the neck 10. with an enlarged portion 11 horizontally'disposed and forming a seat for a sliding valve 12 and also provid ing a seat-13 for the reception of the'tubular arm 14 connected to the loud speaker 15 flh V radio apparatus.

The valve 12 1s provided an opening 16 therein adapted to form a continuous passageway with the tone-arm 6 and the neck 10.

The valve 12 is further provided with a curved opening 17 having one end adapted to provide a combined drawings in which we Referring now to the drawings, 1 desig-' a nates a suitable cabinet containing a phonograph designated AND RAnI'o APPARATUS.

y registrwith and form a smooth continuation of the neck 10 and the other end of which is adapted to register With and-form a smooth continuation of the arm'l l.

The valve 12 as plainly shown in Figs; 2 and 1 is slidablymounted in the enlarged portion 11 of the neck-10 and it is adapted to beslid therein so'thatfthe opening 16 may be brought in alignment with the'opening in the neck 10 and in the tone-arm 6','or the opening 17 may be ,brought'into alignment with the openings in the neck 10 and in the arm 1 1. It will be understood, of course, that the loud speaker 15 is connected to the radio apparatus 3'by any suitable means. The upper part of the neck 10-is connected to the motor-board 18 and the valve 12 is adapted to be operated from the outside of the cabinet by means of a push rod 19- connected thereto and extending. through one wall 20 of the cabinet, being provided externally of the cabinet with a suitable handle v21. Suitable means may be -,prov1ded to limit motion of the valve to insure that the openings 16 and 17 respectively are brought to the-correct positions in registry with the neck 10. This means may consist of -'11"in. the neck 11. The valve serves as a means to modify the tone of the reproduction from either the phonograph or the loud speaker, this result being achieved, of course,

by sliding the valve to increase or decrease the size of opening through which the sound may pass into the neck 10.

'Fromthe above description will be apparent that we have devised a phonograph pli'fying horn may be employed, with either the phonograph orthe'radio apparatus; by means of a simple adjustment from the outside'of the cabinet in which the apparatus is andradioapparatus in which'the same 'amcontained, and thatthe, same means may be employed to modify the tone of the reproduction in a very simple and-efficient manner.

We areaware that changes in the form, construction and arrangement of parts may be, made without departing from the spirit and without sacrificing the advantages of the invention and we reserve the right to make all such changes as fairly fall within the scope ofthe following claims.

We claim 1. In a device of the character described, an oscillatory tone-arm, a fixed amplifying so a pin12 on the valve 12 and engaging a slot I means comprising a pin on said valve en-i gaging a slot in said neck.

2'. In a device of the character-described,

-an amplifying horn, a phonograph reproducer, an arm, a radio loud spea rco'nnected to the arm, a neck interposed between the horn, the reproducm' and the arm, a horiQ zontally disposed valve seatinthe neck, a) one-piece valve slidably disposed in said seat and 'having independent passageways to connect the reproducer or the loud speaker with the horn, means for adjusting the valve, and means arranged on said valve. and enof thevalve.
